Arsenal celebrated their first Premier League win of the season under new manager Unai Emery after coming from behind to beat London rivals West Ham.

A Nacho Monreal strike, Issa Diop's own goal and Danny Welbeck's stoppage-time effort enbaled the Gunners to bounce back from their opening two defeats after Marko Arnautovic had fired West Ham into a 25th-minute lead.

Monreal equalised five minutes later, drilling a fierce shot from eight metres past two defenders on the line after goalkeeper Lukasz Fabianski parried Hector Bellerin's cross into the defender's path.

Arsenal took the lead when Diop's poor clearance resulted in Alexandre Lazazette's cut-back cannoning off the defender's body into the net and Welbeck sealed the win after Bellerin's cross gave him time and space to beat Fabianski from close range.

FT: And that’s that. Unai Emery collects his first Premier League win as Arsenal manager. As for Manuel Pellegrini, he’s yet to pick up any points and a tricky fixture against Wolves is up next.

ARSENAL 3-1 WEST HAM - WELBECK

92: Game, set and match. Substitute Danny Welbeck rounds things off with an injury-time goal.

Hector Bellerin races clear down the right before sending a low cross that goes through the legs of Masuaku before Welbeck slots home.

90: Papastathopoulos is now booked for stopping West Ham from taking a quick free kick. Eventually Anderson runs at Arsenal and drills a low cross across the six-yard box but nobody took the gamble.

89: Jack Wilshere collects a booking for a foul on Lacazette. Not the most enjoyable afternoon for the former Arsenal man.

88: The Emirates crowd are getting restless in the closing stages. West Ham continue to break forward in search of an equaliser. Anderson picks out Hernandez but Mustafi clears.

85: All action here! First Fabianski keeps West Ham hopes alive when saving a wonderful shot from Ramsey. A few moments later Felipe Anderson breaks down the other end. He looks to find the onrushing Perez, but the former Gunner fires wide.

83: Booked! Fredericks slides into Monreal. He’s actually been pretty good for the visitors today.

80: Balbuena bundles into Welbeck, who has made a real impact since coming on, but Graham Scott isn’t interested. Correct decision.

78: Nice stuff from the hosts as Ramsey flicks it over to Welbeck in the penalty area, but his header is straight at Fabianski.

76: West Ham make a change with Yarmolenko replacing Snodgrass. Welbeck comes on for Aubameyang.

73: Close! Arsenal nearly put themselves out of sight through Aubameyang. The forward makes himself a few yards before fizzing one towards goal that deflects off Diop and goes wide. Nearly a brace of own goals…

The Hammers fail to clear and Ramsey nods the ball back into the danger area. Lacazette is aiming for Aubameyang in the middle but Diop is slightly ahead of the forward and the ball flies in off his stomach.

63: Lucas Perez, the former Arsenal man, replaces Antonio for the remainder. He gets a decent enough reception from the Gunners fans.

HT: Two sides who are both vulnerable at the back are locked at 1-1. We could easily have seen more goals, and i suspect we will in the second half.

46: West Ham should be leading 2-1. Arsenal asleep at the wheel. Antonio prods it through to Arnautovic in an offside position. He allows it to run through to the overlapping Anderson, who drills low at Cech.

44: There’s quite a lengthy pause in play as Xhaka and Snodgrass collide. End of the earth kind of stuff that. Both look fine to continue.

41: Pierre-Emerick Aubameyang goes down under a strong challenge and has his hands over his face. It’s hard to tell how bad this is. Standby for a miraculous recovery…

Diop went with his studs and collects a booking. The free-kick goes straight into the wall from Mkhitaryan.

39: Antonio cuts inside before curling a 25-yarder wide of Petr Cech’s post. He looks a bit too keen today. Pierre-Emerick Aubameyang then looks to smash one but he’s sent that over the bar.

36: Oooooh, Manuel Pellegrini will NOT be happy with that. Marko Arnautovic looks to be through one-on-one with Petr Cech but he’s flagged for offside. He scores the chance anyway, and the replays show… he’s a fraction, just a fraction offside.

How Arsenal allowed a 2 vs 2 situation from a long punt forward is beyond me.

33: Nearly a THIRD goal. These defences are just atrocious. Antonio wanders into Arsenal territory but ignores the run from Arnautovic and shoots instead. Cech saves.

25: Things don’t get any easier for Arsenal. Manchester City, Chelsea and now West Ham have taken the lead against Unai Emery’s side.

It’s no less than they deserve really. Felipe Anderson drives forward before finding Marko Arnautovic, who drives in a low shot past Petr Cech.

How Anderson was allowed to stride 40 or 50 yards upfield without being closed down is incredible.

24: Panic in the Arsenal defence. Where have I heard that before? Anyway, Mustafi and Papastathopoulos fail to clear Snodgrass’ cross from the right but the ball kindly pops up for Cech. No immediate sign of a goal at the Emirates today.

21: After a squirt of magic water, Monreal continues. Unai Emery would be in a real pickle without the Spaniard. Maitland-Niles and Kolasinac are both sidelined already.

18: It’s not looking good for Nacho Monreal. He’s come off worse in that collision and the medical staff are on the field.

17: Ouch! Monreal and Fredericks are both left on the deck after a crunching 50/50 tackle. The visitors continue and nearly create an opening for Antonio, but Guendouzi was on him like a flash.

14: Arsenal are looking vulnerable at the back. Bellerin concedes a free-kick on the left, but Anderson’s delivery is awful and the Spanish full-back heads it clear.

11: Disallowed goal! Arsenal have the ball in the net but it’s disallowed for offside. Bellerin drills a cross into the penalty area where Fabianski parries Mkhitaryan’s snapshot over to Ramsey, who nods into an empty net. Just offside.

9: Wilshere fouls Guendouzi and concedes a free-kick just outside the penalty area. Mkhitaryan curls the free kick into the area, but Diop clears.

6: West Ham break at speed with Arnautovic leading the charge down the flank. he eventually delivers a cross but Cech gathers with ease.

3: Arsenal are bossing the possession statistics in the early stages as West Ham sit back and allow them time and space. Good atmosphere in the stadium, louder than usual.

Oh and just the 150 seconds for Carlos Sanchez to commit his first foul of the match…

ARSENAL 0-0 WEST HAM

1: OK, we’re underway folks. I’ll send my best wishes to the poorly Mesut Ozil after the match. Depending on the result, of course…

14:57: I’ll have all the goals and scorers from the other three Premier League fixtures at the top of the page throughout the afternoon. So keep an eye on that and don’t forget to refresh the page from time to time.

We’ll also be covering the Liverpool vs Brighton match later this evening. I’ll provide you with the link later. OK, shameless self-promotion over!

JACK’S BACK…

14:53: Jack Wilshere runs out at the Emirates Stadium as an opposing player for the first time this afternoon. Someone grab me the tissues!

Wilshere opted to leave at the end of his contract after a 15 minute conversation with Unai Emery.

"I spoke with him for 15 minutes here in Colney before he left," Emery said. "The first thing for me is I have respect for his career here. And then, he chooses what the best was for him in his future. It's for that, on Saturday, I know that here, the supporters like him and have this respect also.

"I think there is a good reception for him here. Then we are going to play and we are going to think after that, for us to win. But I hope the best for his career."

Kim: So poor old Mesut Ozil is "ill" again. More likely, Emery told him to work hard in training and he threw his toys out the pram, did anybody see his little sulky reaction when he was subbed at the Bridge? The sooner we are rid the better.

Ian: Mesut Ozil ill again? In other words today is one of his designated days off...and Granit Xhaka starting again, when will this end.

Keith: Mesut Ozil is "ill" yet again. Getting beyond a joke at this stage. Only so many times you can defend the same person. Between poor performances on the pitch and illness it's nowhere near good enough for a professional.

OFF THE MARK?

14:50: While Unai Emery had good reason to curse the Premier League fixture computer for two tough opening fixtures, the new Arsenal boss could hardly have wished for a better game this weekend to get some points on the board.

Manuel Pellegrini's side have also lost their first two games, with a predictable thumping at Liverpool followed by a dispiriting home defeat to Bournemouth.

Stadium issues continue to muddy the waters for the unhappy Hammers and Arsenal, who should have scored five in the first half against Chelsea, will be confident of claiming a first win.
